Application led July 9, 1908. Serial No. 508,688.

To all whom it may concern:

Be it known that we, WILLIAM NELSON and CHARLES O. CHURcHiLL, citizensof the United States, and residents of Binghamton, in the county' ofBroome and State of New York, have invented certain new and usefulImprovements in Valves, of which Vthe following is a specification,taken in connection with the accompanying. drawings, which form a partet' the same. l

This invention relates to valves and more particularly to the internalmechanism of such valves. f

In the accompanying drawings showing illustrative embodiments of thisinvention 'and in which the same reference numerals refer to the similarparts in the several ligures,- 4`igure 1 is a vertical section of` ourimproved valve 'showing the wedge or gate closed; Fig. 2 is a verticallsection at right` angles to the section shown in Fig. 1andfsubstantially on line 2--2 of said figure, looking in the directionof the arrows; Fig. 3 is a horiz'ontal section on the line 3-3 of Fig.1, looking down in the ing a modied form of construction; Fig. 7

l 11 is a plan view of a locking ring provided with recesses instead oflugs; Flg. 12 is a plan view of Astill another form of locking4 member.y

In the illustrative` embodiments of this invention shown in thedrawings, 1 is a valve of any suitable construction. For purposes ofillustration it is shown of the stationary spindle ty e, though ofcourse 1t 1s to be understood) that a rising spindle could be used ifdesired, and that a type of valve may be used in which the bonnet 1sbolted instead of screwed to the body ortion. 'These are Vsuitablemet-al or alloys of any not. enter into our invention andl'thereforeonly one form of valve operating mechanism is illustrated.

Specification of Letten Patent. Patented Digi. 29, 1910.,

We have shown our invention, as noted,

.with screw threads 4 upon the arm'5 of the body member 6. This bodmember 6 is shown provided with two ot er arms 7 and 8 respectively,which are suitably tapped for the reception of ipes, all as wellV knownin the art. The bo y portion is also provided with valve seats 9, 9, andeach valve seat is provided with a seat ring 10 having an internal'diameter substantially that of the valve seats 9, 9. These seat rin sma be formed of any suitable materia suc as asbestos, hard rubber,leather or combinations of the same, or may be made from an metal, 4a las found convenient or ex edlent. These seat rings may be given di erentcontours,

but preferably weA provide them with a flan e 11, and with an externalinclined or beve surface 12. l l

Various means may be used to hold the seat rings 10, 10 to the valveseats 9, 9. For

instance concave lugs 13, 13 may be formed in the body member, Figs. 1,2 and 4, preferably, though not necessarily, being cast integral withthe body member 6 at a suflieient distance from the valve seats 9,- 9

to form recesses 14 within which the-flanges 20 adapted to .be forcedthrough t e open side 17 of the head 16. .This head is rovided withinwardly projecting shoul ers 21 to engage with the head 20 of the nut19. This arrangement insures the connection between the nut-19 and thewedge or gate 15, but the connection is such that the parts can bereadily disconnected when desired, by slipping the nut 19 laterally outof vthe crown 18 and through the open side 17 of the head 16. This nut419 coperates with a' screw threaded spindle '22, which in the -fo'rmshown ,is a non risin spindle, or as known 1n this art 1s a stationarone,

. being provided with a-iange 23 hel to the bonnet 2 by screw threadedcap means of a screw' threaded thimble 24 which is also provided at itsupper end with a recess for any suitable packin 25 and a bushing 26,both of which are he d in place by means of an internal the spindle 22is provided with a andvwheel 28 secured to the spindle in any sultablevmanner such as by a nut 29.

To insure the vproper movement of lthe wedge or gate we use a suitableguiding mechanism. .Such guiding mechanism may be of various forms; thepreferred construction being inwardly extending ribs 30, 30

.i which are secured to the bodymember 6 in any suitable manner butpreferably cast integral with it. lThese ribs coperate with the`recesses 31, 31 formed on opposite sides of the ate or valve 15, seeFig. 3 and also dottedzines 'on Fig.,- 2. It is to be understood,however, thatl this arrangement may be reversed such as shown in Flg. 8,where the body member is shown provided with grooves 32, 32 in theguides 41, 41, within which operate the lugs or projections 33,

33 carried by the wedge or gate 15.

. distinct from the bonnet 2. It willtherefore vanta I of the anges-llof the s'eat rings 10, 10 ht' be readilylseen that by Asuch aconstruction the seat rings are securely held in place even when thebonnet `and wedge are removed, which in practice is found to be of greatad- In epreferred form, the lower portion in the recesses 14,14. Theserecesses 14, 14

arepreferablyof sucient de th and extend the-side of t e bodymember 6 tolioldpthe seat rings 10, 10 1nv place` even when the axis of the valvewith refer-I enceto the'pipe lineis vertical.'4 Further-` more, itv isnot essential that the ylugs 13, 13 be/eontinuous. -They may be formedof a lurality of smaller lugs 60, as shown in ig.6.; `The upper portionsof the'a 4ing curved ends 35, 35 and downwardly ex- 27. The up erend of`seance upper portionof the seat .rings-1Q, 1lWe so preferably,thou'gh'not necessarily, forni the concave surfaces 37, 37 of the legs36, 36

beveled,` as at 38, to coperate'with `the bevel or incline Surfaces 12on the seat rings 1.0, 10, the bevels being such that' any downwardp'essure upon the cage 34 will cause the vel surfaces 38 of theA concavesurfaces 37 to `tend to move downward on the inclined or beveled surface12 of the seat rings.V 10,' 10, whichgwilhmore firmly press the, ringsagainst their seats 9, 9 in an obvious manner.

Various other forms of cages may be used, .such for Instance as'shown1n-F1gs..8 and 9,

where thefcage is formed of .two members 39, 39 having arms 40, 40whichare adapted to take on opposite sides of theguides 41v 41 which aresecured to the body member 6,

preferably, though not necessarily, by lbeing cast integral with it.v Inthis form the cage is made of vtwo members 39,. 39 each of whichcontacts with one of the seat rings and is held in itsoperativepositionv bythe same locking element or ring that` is used to lock ghepreferred forni of cage to the body mem- In some instancesfwe may uSeacage 42 provided with downwardly extendingears 43, 43, Fig. v 10, inwhich are carried the seat. rings 10, 10. f

ln all forms of'our device the cage o1l holding-member, whether it besuch a cage as 34 or 39 or 42, or any variation or equivalent e of them,is securely held in place in the body member 6, by means of some lockingeiement which is .separate and distinct from the bonnetA 2, o'r itsequiyalent. lathe-'preferred construction, to which ourinvention is notto belimited, this locking element isin the form of a locking ring44.provided with screw threads to coperate with. the screw .threads .4inthe arm 5. of the body-member 6.

This ring 444 may eitherA be .provided with lugs`45, 45 Fig. 3, orrecesses'46., 46,= Fig. 11,

to. coperate with any Spanner orlt'ool which will cause it to `lock .thecage to the body member 6 irrespectivey of theybonnet 2, las

shown for instancen Figs. 1, 2, 3 and 4. This lockingjmember may beformed in many other ways. For instance, it may be formed as a .splitIlocking ring. 47, Figs. 6

and 7, having for` instance inwardly extending lugs `48, 48 .which may`bepressed toether with any suitable tool toA permit it to he withdrawnfrom the kscrew threads of the arm 5. In some instances it .may befounddesirable to form this locking member in the form of a fiat spring49 preferably,

11, 11 coperate with af cage -or holdlngv e' f member 34,-such forvinstance as'Fig. 5.. In'

. the preferred construction this cage 'consists' Aof-a substantiallyrectangular member hav.v

though not necessarily,ma o metal, such for;V instance asshown4 in Fig.12. 'This spring isprovided with an.. opening ,50 to pernllt the'passage 'of `the. v vedgey with its Y spine. In al1-these dierentformait willbe seen.

that' in' accordance with .our invention, the

V sition and t at the lockingpelement, of What-y ever shape it may beformed, securely holds the` cage and the seat rings to the body member6, irres tive of the bonnet; and that the withdrawal of the bonnet andWedge or gate does not affect the adjustment or position of the seatrings.

Having thus described this invention in connection with the severalillustrative emthe vbodirnents thereof to the details of which We do notdesire to be limited, what is claimed as new and what it is desired tosecure by Letters Patent is set forth in the appended claims.
